DESCRIPTION: Flexera InstallAnywhere could allow a remote attacker to execute
arbitrary code on the system. The application does not directly specify the
fully qualified path to a dynamic-linked library when running on Microsoft
Windows. By persuading a victim to open a specially-crafted file from a WebDAV
or SMB share using a vulnerable application, a remote attacker could exploit
this vulnerability via a specially-crafted library to execute arbitrary code
on the system.
